Check Digit Verification of cas no

The CAS Registry Mumber 37949-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,9,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 37949-03:
(7*3)+(6*7)+(5*9)+(4*4)+(3*9)+(2*0)+(1*3)=154
154 % 10 = 4
So 37949-03-4 is a valid CAS Registry Number.

Two-carbon ring expansion of 1-indanones via insertion of ethylene into carbon-carbon bonds

Xia, Ying,Ochi, Shusuke,Dong, Guangbin

supporting information, p. 13038 - 13042 (2019/08/26)

A rhodium-catalyzed direct insertion of ethylene into a relatively unstrained carbon-carbon bond in 1-indanones is reported, which provides a two-carbon ring expansion strategy for preparing seven-membered cyclic ketones. As many 1-indanones are commercially available and ethylene is inexpensive, this strategy simplifies synthesis of benzocycloheptenones that are valuable synthetic intermediates for bioactive compounds but challenging to prepare otherwise. In addition, the reaction is byproduct-free, redox neutral, and tolerant of a wide range of functional groups, which may have implications on unconventional strategic bond disconnections for preparing complex cyclic molecules.
